Timo Glock: That was just a really difficult session. It was very hard to find a good balance and I was far from happy. The main problem was as each session went on, the track just started to fall away. That made the second and third runs very difficult and everyone was making mistakes. In the end I just got the lap together for P11 and we were unlucky not to reach the top ten. It would have been good to make it back into Q3 but it just didn't work out. Now we will have to see what happens in the race. It is usually possible to overtake here but if there are similar track conditions it could cause major problems.

Jarno Trulli: Qualifying was exceptionally difficult today because the track conditions were a disaster. The surface was breaking up and getting worse with every lap. I don't know what was going on but I did my best lap at the beginning and then I couldn't repeat it any more. I spun on my quickest lap at the start of Q2, otherwise maybe I could have been in the top ten. But after that the track just got worse. Today was all about getting a clear, lucky lap. I don't know how the race will go but the track surface is a huge concern.

Pascal Vasselon - Senior General Manager Chassis: This is the first time that we don't have one of our cars in the top ten so it was obviously our worst qualifying of the season so far. The grip level was already low, which is typical for Montreal, but it seems that it went one step worse during qualifying because of the high track temperatures. The asphalt was breaking up, making our situation complex. Still, the conditions were the same for everyone so we got something wrong and we have to investigate. The tyres were closely matched yesterday but today's higher temperatures changed the relative ranking of the two compounds, meaning different teams chose very different combinations. We now have a lot to analyse in preparation for tomorrow.
